Urdhva Mukha Paschimottanasana (Face upward stretch of back of body)

You can enter this posture via the transition posture of holding around the feet (fingers underneath the feet and thumbs on top) and rolling on to your back with the feet over the head and then inhaling rolling up into the posture. Or you can simply lift the feet off the floor from a sitting position.

Inhale as you lengthen the spine and exhale draw the legs towards you and your forehead (or chin) toward the shins. Try not to pull with the neck and relax your shoulders.
